    Treaties themselves have no power internally without enabling legislation. Congress is not obligated to pass enabling legislation, to make it conform to the actual treaty language if they do pass it, or to refrain from repealing it. Courts can strike the enabling legislation (or any attempt at direct application of treaty language to the international activity of US citizens or entities) for unconstitutionality, interpret it into impotence, or set up impossible enforcement roadblocks, as easily as they do the same to federal law.

  3. Treaties do NOT trump federal law or Constitution. on Leaked ACTA Treaty to Outlaw P2P? · · Score: 3, Informative

    Typical ... Sneak it in the back door via treaties that trump sovereign laws.

    Treaties do NOT trump federal law or the Constitution.

    When a treaty requires some internal law change to implement its provisions, that can only happen if congress passes such laws. Congress is not obligated to pass such laws or refrain from repealing them. Laws implementing a treaty are just as subject to being struck down as unconstitutional as any other law.

    The idea that treaties are a way to effectively amend the Constitution by an easier procedure comes from a common misreading of the "supremacy clause" of the Constitution. What the clause ACTUALLY means is that the Constitution, federal law, and treaties, each trump state/county/local law when they conflict (and the laws or treaties are constitutional).

    The supremacy clause from article VI:

    This Constitution, and the Laws of the United States which shall be made in Pursuance thereof; and all Treaties made, or which shall be made, under the Authority of the United States, shall be the supreme Law of the Land; and the Judges in every State shall be bound thereby, any Thing in the Constitution or Laws of any State to the Contrary notwith-standing.

    But see also article III Section 2:

    The judicial Power shall extend to all Cases, in Law and Equity, arising under this Constitution, the Laws of the United States, and Treaties made, or which shall be made, under their Authority;

    Note how, in both, the treaties are subordinated to the Constitution and how in article III they're also clearly subordinated to federal law.

    IMHO. If you're going at 1/2 C, the material will go too fast for you to able to collect enough quickly enough to fuse it.

    Fusion is proportional to the pressure x density x confinement time product. Pressure and density both go up and confinement time goes down with the first power of the speed. So power goes with v*v/v, or also up with the first power. (Material collected also goes up with speed but I think that's already accounted for in density.)

    If you get it to produce power at any speed it will produce MORE power if it's going faster. (Which is what you expect, since it would generate no compression and thus no power at all if at rest with respect to the interstellar gas supply.)

    Relativistic time and space distortions also work in your favor at very high speeds. They both make it appear to you that you're collecting more fusible material.

    The field itself compresses the hydrogen hard enough to fuse. Since the reaction is in free space, it would explode in every direction, rather than be directed so you can harness the assymetry. You'd need to have an Orion-style push plate or a solar sail to get any acceleration out of it.

    Nope.

    Just as you have a big magnetic (or whatever) forward-facing funnel out front to redirect the incoming hydrogen, compressing it into a narrow (fusing) stream, you have a big rear-facing funnel out back (like a giant, invisible, rocket nozzle) to redirect the expansion of the now hotter and expanding stream into a rearward-directed jet.

    It's just like most other heat engines: Apply work to compress the gas, add heat, extract (more) work as the hotter gas expands with more pressure than when you compressed it. The forward thrust against your nozzle is more than the rearward thrust against your scoop, even if only by a small percentage. Thus you keep accelerating until the percentage of losses from other issues matches the percentage of gain from the fusion, just as an internal combustion engine can run as long as the mechanical power gained from each cylinderfull of fuel-air mix is greater than the friction losses, even if the power temporarily borrowed from the flywheel to compress it is many times the gain.

    WarGames was responsible for what Knight calls the Great Hacking Scare of 1983.

A magazine article suggested that computer modems be 'locked up' just like firearms, to keep them out of the reach of teenagers.

And the TV executives were concerned about anything that pulled people's eyeballs away from the boob-tube (and money from their advertising rates). So there were a lot of shows that slammed the new distractions: Personal computers, networking (especially bulletin-board systems), electronic games, etc.

    Similarly a few years further back, when they did the same bit on cable TV - when the separation was still more pronounced and they were worried about losing audience to paid programming such as commercial-free movie channels.

  9. Re: Ramscoops: I think the analysis has a bug. on New Superconductor Found "Immune To Magnetism" · · Score: 4, Interesting

    A somewhat off-topic digression:

    The conventional wisdom on Bussard Ramjets (included in the wikipedia article) is that they reach a terminal velocity due to the drag of collecting the fuel - and asymptotically approach their exhaust velocity. IMHO that's incorrect.

    The bug is that the calculation assumes that they must accelerate the collected hydrogen to the velocity of the craft before fusing it, then depend on the fusion energy to re-accelerate it as exhaust.

    However, as with the collected air in chemical ramjets, the momentum of the collected material does not need to be discarded. It can be fused on the fly through the ramjet, retaining its original momentum along the flight path (relative to the vessel). Thus the energy of fusion can be applied to accelerating the reaction products toward the rear. None is needed to replace the momentum allegedly lost capturing the fuel.

    Now SOME of the axial momentum of the incoming fuel is traded for radial momentum to collect it. But the energy of that "lost" momentum is converted to pressure and temperature, compressing the material like any other gas. There is a drag on the scoop field from this. But when the exhaust expands again after the reaction there is a corresponding thrust against the nozzle field, reconverting the radial expansion of the reaction products to rearward velocity and recovering the "lost" momentum.

    If this whole process were lossless there would be no top end to the kenetic energy the ramscoop could accumulate. With less than 100% efficiency in reapplying the compression energy to the mass (both from lost energy and lost mass) there is some drag from collection that is not recovered. (For instance: Mass lost as neutrinos is a non-trivial fraction.) So there may still be a speed limit. But it can be far higher than that calculated by assuming you "stopped" the gas when you "caught" it.

For his business partners this might be never.)

    Right now, diode lasers are among the most efficient (if not the most efficient) light emitters available. I'm guessing the winner, if there is one, will involve a laser or three plus diffusers/despeckling to get general lighting.

    "Despeckling" means spreading the frequency of the light. The speckle comes from interference patters from the monochromatic light from the laser bouncing off surface textures. Broadband sources have speckle in each frequency, too. But the speckle from a swath of minutely different frequencies averages out to a non-speckled reflection.

    So combining a laser with nanoparticles to efficiently swap the energy around between frequencies until it's smeared out into a plesant white light should do the job. B-)
